I'm new to using the embedded Cortex-M parts from TI. I'm looking at one of the Tiva parts with Ethernet and I would like to put a networking stack on this. I see that TI provides TI NDK, but it appears that it is no longer being updated. Since the NDK doesn't get updated I'm worried about security vulnerabilities. Does TI provide anything else that would provide me a networking stack which would provide DHCP, PPP, and NAT? If TI doesn't provide anything else then could you offer any other alternatives that would work well and stay current?
